Thank you for your welcome. I have used TE and TL a bit and thought I should try TN.
I just went through your photos and you have a great talent for wildlife! I have tried to capture birds before without great results so I know it's not as easy as it looks.
I have to add that you have great taste in gear. I am a Canon fan and the 5D is a superb camera. Not to mention your lens too. I am sure you can get out there and bring the birds in without scaring them away.
Thanks again for stopping by and leaving a note,
